ABSTRACT:
A membrane-electrode assembly comprising a cathode catalyst layer for reducing an oxidant gas, a polymer electrolyte membrane and an anode catalyst layer, the polymer electrolyte membrane being sandwiched between the catalyst layers, wherein the cathode catalyst layer exhibits super-water-repellency. The disclosure is also concerned with a method of manufacturing the membrane-electrode assembly and a fuel cell using the membrane-electrode assembly.
